I have a laptop which has L9, LX and Garageband on and I'd like to get rid of the lot of them and free up the space for other purposes (one of which might be a minimal LX installation). I've been looking around online and apart from the fact that's files lying around all over the shop I can't find an authoritative list of what needs to be deleted. Lots of ads for programs to do it for me, mind ...

Can anyone recommend a site that has usable and accurate instructions for this task? Or, in desperation, a bit of software that would do it without screwing up anything else?

And the various Logic preference files (search for "logic") in/Users/*YOU*/Library/Preferences//Users/*YOU*/Library/Preferences/Logic (if you have this)

That'll take care of all the important stuff, provided you haven't chosen to install or move content to other locations (you'll have to sort those out yourself).

Edit: I just pointed CleanMyMac (respected uninstaller) at LPX to see what it suggested. It only really gets the app, basic preferences, the root App support Logic folder, and a cache folder (/Users/*YOU*/Library/Caches/com.apple.Logic10), some logs and the odd content installer lying around but misses a lot of the other content.

Doing it manually however works fine...

Note: for Garageband you'll be looking for /Garageband folders, rather than /Logic, obviously enough.. But GB shares a lot of content with Logic anyway (eg Loop content).
